Also shot was 19-year-old Josh Garza, of Dyer, Ind. Garza was moved from Advocate Christ Medical Center in Oak Lawn, Ill., because a reporter found his room and authorities feared for his safety after the incident.

A third construction worker escaped by running into a nearby cornfield.

The gunman then traveled 13 miles to the residence of farmer Keith Dahl and shot him after engaging in a conversation about honey bees, police said. Ballistics technicians observed similar characteristics from bullets used at both incidents.
